Tire tread



FIG. 1 is a perspective view of a tire tread, showing my new design;

FIG. 2 is a partial side view thereof; and,

FIG. 3 is a front view thereof.

The broken line showings of the sidewall from the inner bead to the tire tread are included for the purpose of illustrating environment and form no part of the claimed tire tread. The tread pattern is understood to repeat uniformly throughout the circumference of the tire. The other side of the tire is the same as the view illustrated in FIG. 2. 

CLAIM The ornamental design for a tire tread, as shown and described.
